` To all whom it may concern.'

Be it known that I, COLVINL. JOHNSON, a citizen of the United States, and a resident of the city of St..Louis,4 in thecounty of St. Louis andState ofv Missouri, havev in- "1 vented certain new and useful Improvements in a Disk-Wheel-Carrier Lock; and f--do -hereby declare that the following is a"full`,' 4 clear, and exact description of the same,-

reference being had to the accompanying drawings, and to the numerals ofreference marked thereon, whichflorm a part of this specification.

to an improved type ofa lock orvsecuring a spare disk wheel.on a wheell carrier of an automobile Aagainst unauthorized removal.

It is an object of thisinvention to pro-1 vide an improved disk wheel lock for lock# ing a spare disk wheel on a carrier.

It is also an object of the invention `to. rovide one of the mounting bolts of a vegicle spare wheel carrier with a locking nut.

Another object of the invention is tore- 4place one of the retainingnuts of a spare wheel carrier by a washer and locking nut adapted to be released by releasing a latch l in the locking nut by means of a.. key.

It is a furtherobject of the invention to provide a key releasable lock nut, a grooved washer anda retaining plate adapted to be substituted for one of the nuts of a Vspare wheel carrier to be locked vin place on the carrier a ainst removal except by means of' a roper ey.

Y Vt is an nnportant object of this invention to provide -a simple and effective lock nut carrierlock embodying the wherebyl a spare disk wheel may be locked. upon` a carrier by simplysubstituting the lock nut and a non-rotatable washer member for one vof the carrier nuts.

Other and further important objects oi -.this invention will be-apparent from the disclosures in the specification and drawings.-

The invention'(in a preferred form)` is` illustrated in the drawings and hereinafter more fully described.

YTo lock the spare -d iskwheel on the carrier to prevent stealig thereof, one of the 4 are threaded onto the projecting ends of he 4- plate atv right angles thereto outwardly projecting parallel screw bolts 3 adapted to.

ged upon-the carrier bolts 3 to the 10 0 and replaced by a locking washer and nut. The locking 'washer comprises a plate 9 having t-hree straightedg'esand an inwardly curved or `concaveedge 10.- Integral] formed on the* curved edge of the was er plate .9 is la segment-shaped lip or flange 11. A n open- 'ing 12 is provided in the 'washer plate 9 to permit the sameto be engaged on'a carrier bolt 3 with the'flange 1l' seatedin the groove 8 of the retainingY plate 7. The washer plate 9 is provided with a'circul'ar recess 13 in the outer face thereof. As illustrated 'in Figrires-6v and 7, the washer plate 9 has two diametricall-y opposite-openin s 14 in the bottom of the recess '13 thereo on opposite sides of the opening 12. Theinner face of the washer plate recess is also provided With two oppositely disposedl inclined' arc shaped' slotsor grooves 15 havin the deepest por-v tions thereof at the openings-,14, while the other ends are ush withvthe inner face; of

therecessbottom, 'as sho'wn in Figure '7 The'lock nut comprises a nut, portion or 'casing 16 provided'with oppositely directed integral handles 17. Formed within 'tli'en'ut 16 is' an axial vthreaded passage 18, a recess lor chamber '19, and a locking -bolt'passage'20.

' Mounted within the nut chamber 19 within a collar 27 is" a Akey operated barrel -lock 21 havin a rotatable barrel 2 2 provided with 'a 4key s ot. 'Secured to the inner end of the llock barrel is cam strip or segment .23.
